Crosscode was originally coded in HTML 5. If you don’t believe me, you can play the demo version of it directly from the developer’s website:
http://cross-code.com/en/start The executable that you get from gog.com, steam, itch.io, simply runs that html code through a web browser emulator.
Just ran the web demo using a really old go stream 7 (the thing has an intel atom z3735G) and the game was mostly playable (probably would’ve been more playable if it wasn’t downloading and installing drivers for the Logitech mouse I plugged into it), which was impressive considering that intel atom processors aren’t really designed for this kind of thing, and this tablet was not meant to do this either (it was a miracle that the sole micro USB port it had was able to give my dell keyboard and it’s built-in usb hub power for the wireless mouse dongle).
TL;DR- the system requirements for this game is really, really low. Should run perfectly fine on integrated graphics made over half a decade ago.
